The beef is still all right. Or at least not bad.
Bovine spongiform encephalopathy, otherwise known as mad cow disease, is not suspected in the death of a Marin County woman, according to health officials.
One woman has died and another person is sick with a "rare degenerative brain disorder" that bears similarities to mad cow disease, but the disease itself is not suspected. Nor is there any risk of a contagious spread of the illness, known as Creutzfeldt-Jakob disease, the San Francisco Chronicle reported.
The disease causes early dementia and is always fatal, the newspaper reported.
"We have no evidence that suggests a causal linkage between the suspect cases nor is there any evidence to suggest a risk in food supply," the state public health department said in a statement.
Creutzfeldt-Jakob is very, very rare: 300 people nationally and 30 in California are afflicted annually. The disease "comes up suddenly and for no known reason" or from genetics, the newspaper said.
The disease, which causes a buildup of proteins in the brain, has no cure. Including cows, which, at least for now, are A-OK in Marin County.
